Windows 10: Second monitor won't display - Windows 10

As the title says, I'm having an issue where the second monitor in my set-up won't display in Windows.


Configuration:

Motherboard: Asus Sabertooth A170 Mark 1

CPU: Intel i5-6600K

GPU: ASRock Phantom Gaming Radeon RX590 running Radeon Adrenalin 19.2.2

Monitor 1: Alienware AW2518hf (connected w/ DP)

Monitor 2: BenQ GW2765 (connected w/ HDMI)

Windows 10, fully patched


Problem description:

As soon as the loading screen for Windows appears, the BenQ monitor goes black and I get a "no signal detected" message. From that point forward no image ever displays and no setting changes are ever reflected on that monitor.

When in windows, both monitors are detected by the OS and the Radeon Adrenalin software. They can both be seen under "Display Settings" with all the dual monitor options available and configurable.


Steps I've already taken:

1 - Verified that all connections were secure (yes it's plugged in lol)

2 - Plugged the BenQ into another port on the graphics card

3 - Completely re-installed Windows

4 - Completely re-installed the Radeon drivers

5 - Voodoo Sacrifice...

6 - And now I'm here.


I don't understand how it works perfectly in the BIOS (so I know hardware wise it's good and connections wise it's good) but then it goes totally out when Windows starts. With a fresh install and all new drivers, I'm not sure what else to try. Any help is greatly appreciated.

OK. Now I know what ur problem is. Step by step:
1. Go to Catalyst Control Center
2. Click on the word "Graphic" right on top left corner. It will display drop down menu
3. Click on Display monitor and will see the list of monitor at near bottom
4. Right Click the monitor and select "Configure". It will show up the window
5. There will be 3 option to select. Select the middle one and then click on the tab which show the bar with 15%.
6. Drag the bar to max, and the screen will stretch to the native resolution 1680x1050.
7. Also click the tab with showing RGB drop down list and select the last one (it will change to image quality for pc).
That's it. Good Luck.

 

Windows 10 doesn't show native display for second monitor

Hi,

In order to for your Windows 10 to show the native display for the second monitor, you may revert all screen settings back to default, and see if this resolves the issue. If it doesn't, you may try these steps:

• Press Windows key + P.
• If your monitor settings is on Duplicate, try choosing
  Extend.
• If your monitor settings is on Extend try choosing the
  Duplicate.
• Check the resolution if both monitors are showing the same resolution value.

windows Can't detect my second monitor

Hi Max,

Thank you for posting your query in Microsoft Community.

I understand that you are having a tough time working on the computer.

I will certainly help you to resolve the issue.

• 
  What happens when you try to connect the second monitor?
  
• 
  Do you receive any error code/message?
  
• 
  Have you tried to connect the second monitor on a different port?
  

I suggest you to connect second display using a different port available on your PC and check if the second display works. If second display works in other port, then the possible cause for this issue may be discrete video card driver.
